(a) Morphology of desmin-specific (green) skeletal muscle myoblasts of passage 2 in the culture (40x). (b) Proliferation of skeletal muscle myoblasts in culture throughout a single passage for young () and older () subjects. The data (mean ± SEM) for cells from passages 3, 5, and 6 were combined, as the dynamics of cell growth was similar within each of the passages. ; ; compared to the first day of cultivation.
